The ● denotes specifications which apply over the full operating
temperature range.
Note 1: Typical parameters are defined as the 60% yield of parameter
distributions of individual amplifiers, i.e., out of 100 LT1169s (200 op
amps) typically 120 op amps will be better than the indicated specification.

readings are extrapolated to a warmed-up temperature
from 25°C measurements and 45°C characterization data.
Note 3: Current noise is calculated from the formula:

= (2qI

)
1/2
where q = 1.6 × 10
–19
coulomb. The noise of source resistors up to 200M
swamps the contribution of current noise.
Note 4: Input voltage range functionality is assured by testing offset
voltage at the input voltage range limits to a maximum of 2.8mV.
Note 5: This parameter is not 100% tested.
Note 6: Slew rate is measured in A
V
= –1; input signal is ±7.5V, output
measured at ±2.5V.
Note 7: The LT1169 is designed, characterized and expected to meet these
extended temperature limits, but is not tested at –40°C and 85°C.
Guaranteed I grade parts are available; consult factory.
Note 8: ∆CMRR and ∆PSRR are defined as follows:
(1) CMRR and PSRR are measured in µV/V on the individual
amplifiers.
(2) The difference is calculated between the matching sides in µV/V.
(3) The result is converted to dB.
Note 9: The LT1169 is measured in an automated tester in less than one
second after application of power. Depending on the package used, power
dissipation, heat sinking, and air flow conditions, the fully warmed-up chip
temperature can be 10°C to 50°C higher than the ambient temperature.
